Even three years after the ambitious Right To Education (RTE) came into force, nearly 20% of government schools are yet to have professionally qualified teachers, according to a study conducted by the HRD ministry. The study for 2012-13 revealed that the percentage of professionally-educated teachers in government schools is around to 81%, just one per cent up from the previous year. The RTE Act, which came into force three years back, mandates states to have professionally-qualified teachers in all schools within five years.
